listmonk
Top pickFast, self-hosted newsletter and mailing-list manager in a single binary.
listmonk is a self-hosted newsletter and mailing-list manager written in Go, distributed as a single binary backed by PostgreSQL. It handles large lists, subscriber management, custom fields, segmentation, templated campaigns, and click/open analytics, and sends through any SMTP provider you choose (such as Amazon SES, Postmark, or your own relay). It exposes a full HTTP API and a clean admin UI, and is a strong fit for teams and technically comfortable individuals who want to own their subscriber data and keep sending costs to whatever their SMTP provider charges.
What it does well
- +Single Go binary plus PostgreSQL — straightforward to deploy and low on resources
- +Bring your own SMTP provider, so sending cost is decoupled from any one vendor
- +Full REST API, custom fields, segmentation, and template management
- +Actively maintained with a large community (20,000+ GitHub stars)
- +Your subscriber data stays entirely on infrastructure you control
Where it falls short
- −You are responsible for email deliverability, SPF/DKIM/DMARC setup, and an SMTP relay
- −No built-in visual customer-journey/automation builder as deep as Mailchimp's
- −Requires comfort running a server and PostgreSQL — not a click-to-start hosted service
- −AGPL-3.0 imposes source-sharing obligations if you offer a modified version as a network service
